With just days left to serve on her probation, Teen Mom 2 star Jenelle Evans can’t stay out of trouble, and Breaking Celebrity News has exclusive details on the secret hook-up with ex-boyfriend Kieffer Delp that ended up with a run in with the cops Friday.

“She has spent the past few days with Kieffer shut up in her apartment having sex,” a source exclusively tells Breaking Celebrity News. “She’s only got days left of her probation and now she’s could end up back in jail because she’s not meant to be with him as he has a criminal record.”

Delp only got out prison last month, and he's already causing more headaches for his on-again-off-again-on-again girlfriend as their recent dalliance resulted in a visit from the police.

"Cops arrived at Jenelle's home Friday and chased Kieffer away," a source tells Breaking Celebrity News. "Nothing happened to Jenelle, at this time, but to say the police are sick of her and her drama would be an understatement."
